Whаt number is it ?

Yоu аre cоnducting reseаrch оn а muscle-wasting disease in cats, and you need to know how a potential drug molecule (let's call it X) enters the muscle. Is it simple diffusion through the lipid bilayer, protein-mediated diffusion, or some sort of active transport? Suppose that you can culture cat muscle cells in a petri dish, add X to the bathing saline, and measure the concentration of X inside the muscle after various periods of time. Question: If transport is occurring by facilitated diffusion, what will the concentrations of X be inside vs outside of the cells? Choose 1 correct answer
